I've been working on processing for prototyping for the past 3 months and I have used processing2.0b9, processing2.0b8, and processing1.5.1 on my Windows 7 PC. It was loading and working perfectly fine until 2 days ago. Suddenly, all the processing 2.0 versions don't load at all. The loading image having "Processing initiated by Ben Fry & Casey Reas" loads and then nothing happens. So, here are the things that I tried in the last 48 hours:

(a) Reinstalled the application - 6 times

(b) Reinstalled my Java JRE - 3 times

(c) Tried removing the preferences.txt file.

(d) Tried debugging through the command prompt.

(e) Tried running it in a different destination folder & drive.

Nothing works. Usually, my Windows Task Manager's processes tab shows a "javaw.exe" as soon as a Processing application runs. Now nothing shows up there as well. The weirdest part is that Processing 1.5.1 still opens & runs. My sketches are safe & so are my libraries. But they are rather dormant. The PDE files don't show the Processing icon that it once showed.

I've already lost 2 days in trying to load the IDE/App for Processing 2.0b8, processing2.0b9, & processing 2.0.1. Any help is appreciated.

PS>> Source suspicion: I once loaded the G4P's createGUI() in the draw() function just to experiment. And when I hit the run, it put out a fatal error because I stopped it abruptly through the task manager as the draw() function called the createGUI() function in an infinite loop. I suspect if that termination caused such a problem.

Update: The application seems to be running on the background because after tryring to run the application's IDE, (clicking processing.exe), and finding that the IDE isn't launching, when I tried moving the Processing folder, it says that a File is open in the Folder.
